Movable-type printing was the invention in the 1400’s revolutionized the way knowledge could be spread.
<h3>
What is Movable-type printing?</h3>
This type of printing involves the use of movable components to reproduce elements and letters on paper.
This was adopted by churches through printing of bible and other religious materials and led to the protestant reformation in the 1400s

DNA - Option C.
Gene - Option A.
Chromosomes - Option B.
<h3><u>Explanation:</u></h3>
DNA is described here as the instructions that governs all the characters of an organism. Its actually a macro molecule which is a polymer of different thousands of nucleotides which is present in all cells and contain genetic information for running the characters of an organism.
Genes are described here as series of nitrogen bases governing a particular character or trait. Gene is actually a functional part of DNA which codes for a protein that governs a particular character of an organism.
Enzymes are proteins in nature. They are produced as a result of transcription and translation from DNA, and hastens different chemical processes of a metabolic activity.
The chromosomes are the condensed form of DNA. They are seen in the cells prior to cell division, either mitosis or meiosis. They are half obtained from father and the other half from mother, leading to variations among the offsprings.
C
Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.
Explanation:
Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes. The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.
